I also love many of the names on your list even though I'm not convinced by the combos (love Antonia, dislike Mae)
Actually, most of your combos have one name I like and one I don't care for which is kind of strange.
I love both Beatrix and Isolde though, but BeatrixIsolde sounds a little sharp to my ears. AntoniaBeatrix is better in my opinion, or IsoldeWren...
